Kiss goodbye to deer on farmland.....


We need to increase TB testing on Exmoor, warns MP​

There's calls for an urgent study into levels of TB in the wild Red Deer population on Exmoor - to prevent it spreading to cattle.

Ian Liddell-Grainger says ministers need to launch a study 'if the successes achieved locally by badger culling are not to be reversed'.

Ian Liddell-Grainger says ministers need to launch a study 'if the successes achieved locally by badger culling are not to be reversed'.

Exmoor is home to around 3,000 red deer – the largest herd in southern England – with the animals ranging freely across open moorland and farmland.


The MP said: "Concerns were raised during the early stages of the badger cull as to how many were infected with TB and the matter was discussed again recently at a special meeting of farmers and landowners."

Mr Liddell-Grainger, whose Bridgwater and West Somerset constituency includes two-thirds of Exmoor National Park, said no-one was any nearer to knowing what the true levels of infection were.


He added: "Given that we could be looking at a potentially huge risk to farmed animals I believe we need to start finding out as a matter of urgency.”

He will be submitting his request for a study to both Defra Secretary George Eustice and to the Prime Minister, who grew up on an Exmoor farm.

Mr Liddell-Grainger said an initial step would be to carry out thorough veterinary checks on all deer carcasses found on farmland - and will be submitting his request for a study to both Defra Secretary George Eustice and the Prime Minister, who grew up on an Exmoor farm.

“At the moment farmers are reluctant to report any they find because they have to bear the £100 cost of having them taken away,” he said.

“We need to remove that charge and extend the free collections that currently apply to badger carcasses to deer as well.

“No-one knows the scale of the problem we are facing or, indeed, whether it is physically within our powers to do anything about it. But it would be tragic – not to mention an enormous waste of public money – to have achieved so much success in reducing the incidences of bovine TB on Exmoor if we do nothing about another species which also acts as a reservoir of TB infectivity.

“This is an issue which cannot simply be left on the back burner. The NFU, the National Park Authority and particularly the National Trust, as a significant landowner, must get together and start working out what initial action to take.”
 
I was told by a vet a few years ago that while badgers are known to be maintenance hosts of TB, deer in the UK are considered spillover hosts. How does a study which finds TB in a deer carcass show whether deer are maintenance or spillover hosts I wonder? Or is it based only on numbers/percentage of the population being infected?

Where did you find this article out of interest?
 
Terminology can get itself tied in knots when referring to diseases. Definitive or intermediate, maintainence, end, spill-over, competent/incompetent. It varies with the parasite (infectious agent) the species, the environment and then last, but by no means least, the political point someone is trying to make. Deer can be a host (see below) but the risk of transmission to cattle is probably quite low. The badger-cattle things is two animals constantly sharing the same area, deer are more transitory. I also have a feeling that most deer bTB is relatively walled off in the body, unless th edisease is quite advanced (I'll take advice on that)

The anti badger culling fraternity regularly state that badgers are not a maintainence host for bTB. They are, as are cattle, just as humans were in the Victorian slums. what's the common factor - close living. Apply that to deer and it's no surprise that the herding species have a higher prevalence of bTB, especially fallow. Look to the USA where bTB has been a problem in white-tailed deer, associated with feeding stations (which is why I regularly get cross with people asking about attractants). In Spain, red deer are an issue, as are wild boar - both associated with common feeding/watering areas.

Interesting breakdown of the problem - thanks for that.

Also gave me a shock reading your profile quickly - i thought it said Vegetarian! Thankfully not...

Hmm, when admin suggested the vet tag, we thought it was a good idea. I was all for "Vitnery" but some of our friends abroad (and in the south) may not have understood. We hadn't contemplated confusion with diet!!

Thank you Buchan your response to someone else's question was most informative and has actually answered a couple of questions that were bugging me.
 
Why should they need to pay for a study when all they need to do is talk to APHA and discuss the reported cases of TB by deer stalkers.
As said above, this isn't necessary as in general deer don't tend to mix with livestock.

It’s a good point, as APHA provides regular updates on the bTB situation on Exmoor in response to FoI requests. A quick Google will turn up several recent results. Sadly one can’t see who made the FoI request :-|
 
Hardly scientific but..................when I don't have any badgers I don't have any reactors and the cattle remain bTB free despite relatively good numbers of deer both resident and transitory, some of which I should add have been found to show signs of TB.
 
One farm I shoot on had to to kill two TB infected cows last year. There are no badgers in the area. The vet told the farmer it must have been brought in by deer. Not sure whether I agree but it got me a permission.
